You really need to run 'getmaintainers.pl' on this patch. If you want a
maintainer to see your change, the e-mail has to be directly addressed to them
as well as CC'd to the mailing list, otherwise chances are they won't see it.
Also, as this is the second iteration of the patch, the title should be
versioned, i.e. "[PATCH v2] ..."

As Pierre mentioned yesterday, this is not an existing patch being reapplied, so
you cannot assume people's 'Signed-off-by' on this. Mark certainly won't add his
'Signed-off-by' tag until he merges it into his tree. Also, has Sathya actually
seen this actual change? If not how can you add his 'Acked-by' tag?
If you can make this patch format in-line with normal expectations, then the
code below looks ok to me.
